    15 Expect the compilation to take quite some time! With four 2.5GHz cores (-j4) it usually takes around one hour!

    1723You might want to call cmake to set up the build environment with a different (e.g. faster) compiler like clang:
    … …  
    2935This option is *not* supported anymore in root 6.18. No solution for this exists by now. If you really need it (required to compile the FACT++ online GUI), you must not use this root version by now!

    31 Note that the current version of root (6.14) need !RootNewMacros.cmake during compilation of derived projects which is (only) located in the source directory. Therefore, you must not remove or change the name of the source directory. I hope that will be fixed in the future.

    33 == Saving Space ==
    34 
    35 To save space, after compilation you can create a binary package with `make package`. This will create a `.tar.gz` file. You can then extract this file (`tar xvfz filename.tar.gz`) to any location you like (the default ist `./root`) and remove the build directory (and if you like also the source directory).
     37Note that if you run root from its build directory (not recommended!), root (6.14) need !RootNewMacros.cmake during compilation of derived projects which is (only) located in the source directory. Therefore, you must not remove or change the name of the source directory. I hope that will be fixed in the future.
